Synopsis

Ischemic colitis is defined by a transient compromise in blood flow to the colon that is below its metabolic needs, leading to ulceration and hemorrhage of the mucosa. Hypoperfusion is the most common etiology, leading to nonocclusive colonic ischemia. This occurs most frequently in the watershed regions, which have limited collateral blood supply. Ischemic colitis may also be due to occlusive thrombi in the mesenteric arteries or veins, especially in older individuals with comorbidities such as cardiovascular disease.

The incidence of ischemic colitis is at least 16 per 100 000 people / year; however, the true incidence is likely greater, as many people may not recognize the transient symptoms of ischemic colitis.

Typical presenting symptoms include acute-onset abdominal pain, diarrhea, and rectal bleeding. Risk factors for the development of ischemic colitis include smoking, aortoiliac surgery, myocardial infarction, hemodialysis, and hypercoagulable state.
